Abstract

La présente invention concerne un amplificateur de puissance Doherty à étages multiples et un émetteur, et l'amplificateur de puissance Doherty à étages multiples comprend : un amplificateur de porteuse généralisé (201), qui est un sous-amplificateur Doherty inversé à deux voies imbriquées, et un amplificateur de crête généralisé (202), connecté à l'amplificateur de porteuse généralisé (201), qui est un sous-amplificateur asymétrique imbriqué ou un sous-amplificateur Doherty normal à deux voies imbriquées, l'amplificateur de porteuse généralisé (201) et l'amplificateur de crête généralisé (202) étant agencés dans une forme d'amplificateur de puissance Doherty inversé à deux voies généralisée. Avec l'amplificateur de puissance Doherty à étages multiples, une fonction de distribution de probabilité de puissance de signal (PDF) orientée pour une conception d'amplificateur de puissance (PA) Doherty à plusieurs étages économique est appliquée, et des cellules PA Doherty normales et inversées à 2 voies sont utilisées en tant qu'unités de base pour construire un PA Doherty à plusieurs étages avec un effet d'extension de gain.
